指出机载电子设备的环境温度极值首先应根据设备出现的地理范围和载机的任务剖面进行确定，而不是直接引用通用标准中规定的温度极值。同时，介绍了确定设备环境温度的方法，以及对有关标准中规定的环境温度条件的剪裁和应用 It is pointed out that the extreme value of ambient temperature of airborne electronic equipment should first be determined according to the geographic scope of the equipment and the mission profile of the carrier, rather than directly quoting the temperature extremes specified in the general standards. At the same time, the method of determining the ambient temperature of the equipment is introduced, as well as the tailoring and application of the ambient temperature conditions stipulated in the relevant standards
